DTC Description

INFOID:0000000010702953

DTC DETECTION LOGIC

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crank-
shaft position (CKP) sensor signal to vary, ECM can determine that a misfire is occurring.

The misfire detection logic consists of the following two conditions.
1.

One Trip Detection Logic (Three Way Catalyst Damage)
On the 1st trip that a misfire condition occurs that can damage the three way catalyst (TWC) due to over-
heating, the MIL will blink.
When a misfire condition occurs, the ECM monitors the CKP sensor signal every 200 engine revolutions
for a change.
When the misfire condition decreases to a level that will not damage the TWC, the MIL will turn off.
If another misfire condition occurs that can damage the TWC on a second trip, the MIL will blink.
When the misfire condition decreases to a level that will not damage the TWC, the MIL will remain on.If
another misfire condition occurs that can damage the TWC, the MIL will begin to blink again.

Two Trip Detection Logic (Exhaust quality deterioration)
For misfire conditions that will not damage the TWC (but will affect vehicle emissions), the MIL will only
light when the misfire is detected on a second trip. During this condition, the ECM monitors the CKP sen-
sorsignal every 1,000 engine revolutions.

A misfire malfunction can be detected in any one cylinder or in multiple cylinders.

POSSIBLE CAUSE

• Improper spark plug
• Insufficient compression
• Incorrect fuel pressure
• The fuel injector circuit is open or shorted.
• Fuel injector
• Intake air leakage
• The ignition signal circuit is open or shorted.
• Lack of fuel
• Signal plate
• A/F sensor 1
• Mass air flow sensor
• Incorrect PCV hose connection

DTC CONFIRMATION PROCEDURE

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.

Will CONSULT be used?

YES

>> GO TO 2.

>> GO TO 4.

PERFORM DTC CONFIRMATION PROCEDURE-1

WITH CONSULT

Start engine and warm it up to normal operating temperature.

Turn ignition switch OFF and wait at least 10 seconds.

Restart engine and let it idle for about 35 minutes (except for Europe) or 15 minutes (for Europe).

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Proceed to

ECM-252, "Diagnosis Procedure"

>> GO TO 3.

PERFORM DTC CONFIRMATION PROCEDURE-2

Turn ignition switch OFF and wait at least 10 seconds.

Start engine and drive the vehicle under similar conditions to (1st trip) Freeze Frame Data for a certain
time. Refer to the table below.
Hold the accelerator pedal as steady as possible.
Similar conditions to (1st trip) Freeze Frame Data mean that the following conditions should be satisfied at
the same time.

Driving time varies according to the engine speed in the freeze frame data.

trol mode

Accelerator an-
gle variation
control

ECM controls the accelerator pedal depression speed to make it slower than actual speed. This
causes a drop in accelerating performance and encourages the driver to repair malfunction.
NOTE:
ECM does not control the accelerator pedal releasing speed.

ing

No stratified charge combustion at starting (cold start).

erating

Stops recovery speed control by the fuel cut at decelerating and controls with specified speed.

Idle neutral con-
trol

Stops idle neutral control.
